The Philippine Institute of Volcanology and Seismology (Phivolcs) reported Sunday morning it has monitored a “weak ash emission” event from the summit crater of Mount Kanlaon in the Negros Island Region.
Based on a time-lapse footage released by the state seismic agency, the volcano released a 500-meter grayish plume, which drifted southwest. The smoke was seen almost hiding behind the clouds from the Phivolcs’ Canlaon City observatory.
Alert Level 2 remains over the volcano, indicating increased signs of activity. Under this warning, people are prohibited from entering the permanent danger zone within the four-kilometer radius. All types of aircraft are also advised against flying near the volcano.
According to the latest Phivolcs volcano bulletin, Kanlaon registered 65 volcanic earthquakes over the past 24 hours. It also emitted 1,638 tons of sulfur dioxide (SO2) since October 4, 2025 and a 650-meter plume that drifted northwest.
Mount Kanlaon had its last major ‘explosive’ eruption on May 13, 2025. It had a sudden minor phreatic eruption on September 16, which lasted for a few minutes.
